Single dominant left coronary artery: An autopsy case report with review of literature

Area of Science:

• Cardiology
• Congenital Heart Disease
• Anatomical Variations

Background:

• Coronary artery anomalies are uncommon congenital conditions.
• A single coronary artery is a rare anomaly where one vessel supplies the entire heart.
• Incidence ranges from 0.3-1.3% in coronary angiography and 1% in autopsies.

Observation:

• This report details a rare case of a single coronary artery.
• The anomaly presented with an unusual dominant left circumflex artery.
• The right coronary artery was congenitally absent in this case.

Findings:

• The patient exhibited a single coronary artery arising from the aortic trunk.
• Dominance of the left circumflex artery was noted, supplying the territory typically covered by both coronary arteries.
• Absence of the right coronary artery was a key feature of this anatomical variation.

Implications:

• Understanding rare coronary artery anomalies is crucial for accurate diagnosis and surgical planning.
• This case highlights the spectrum of single coronary artery variations.
• Further research into the clinical significance and management of such anomalies is warranted.
